Show HN: Production Manager App – Offline Payroll and Job Tracker (.exe)

I built a secure offline app to modernize fiberglass insulation workflows. Most construction companies—especially in fiberglass insulation—still rely on paper forms and manual data entry to process installer payroll. It’s slow, error-prone, and wastes time, energy, and paper. The Production Manager App is a closed-source Windows .exe that runs locally, enforces license keys via Gumroad, and auto-generates Excel reports based on job entries. No cloud sync, no external dependencies—just hardened logic built for real-world use. Key features: • Weekly payroll calculation based on square footage, bags installed, or hourly wage • Auto-splitting pay across up to four employees per job • Full job entry interface with builder, model, lot/block, and optional insulation specs • Secure login with salted + hashed credentials • Auto-export to Excel with per-employee sheets grouped by week • Local SQLite database with smart cleanup and de-duplication • Auto-update support (checks for new versions) The app is designed for non-technical users—fullscreen interface, no setup required beyond Excel. Once installed, it handles everything locally and auto-generates payroll reports two days after the pay period ends. License enforcement is hardened: the .exe is encrypted and only unlocks after validating a Gumroad key. No open APIs, no cloud sync, no shortcuts.
